# Current USA LOOP vs SYNA

The clearest difference is rating: SYNA at 3.4 against Current USA LOOP's 2.6. SYNA also leads on update cadence (every 10 days vs every 12 months) and ratings volume (341 vs 19). Current USA LOOP's advantage is review sentiment (28% vs 1%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SYNA holds the better App Store score, 3.4 against 2.6. That said, the two scores are not equally well evidenced: SYNA has 341 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 28% of Current USA LOOP's written reviews are positive against 1% of SYNA's, so the app with the better star average is not the one people write more warmly about.

Current USA LOOP ships an update every 12 months, SYNA every 10 days. The most recent releases landed on September 19, 2026 and September 23, 2026 respectively.
